The coastal tropics comprise some of the most sensitive and yet the most understudied ecosystems in the world. Coastal plains and river valleys are also home to agriculture on a vast scale, and it is not surprising to find that streams and rivers receive the majority of agricultural runoff, carrying the residues of insecticides, fungicides and other pesticides into estuaries and coastal zones. There is a growing awareness of the urgent need to develop strategies to help productive, healthy and economically viable agriculture to coexist with natural resources. Pesticide Residues in Tropical Coastal Ecosystems brings together toxicology experts from around the world to assess pesticide burdens in many of the major food-producing tropical countries. It provides a unique set of case studies, chronicling pesticide usage and its ecotoxicological impact in coastal regions. A practical guide to recent research findings and applications, it is essential reading for environmental professionals, ecotoxicologists, marine chemists and agrochemists.

Pesticides play an important role in controlling pests that carry diseases and threaten crop production. In recent years, however, there has been increased concern about the adverse impacts of pesticides and their degradation products on public health and the environment. A considerable amount of work is being done to develop nonchemical methods of pest control, but it is not yet feasible to dispense with the use of chemical pesticides. Pesticides: Evaluation of Environmental Pollution brings together, in a single volume, current knowledge on environmental pollution caused by pesticides. It helps readers evaluate the effects that pesticide residues have in all compartments of the environment. Featuring contributions by eminent scientists from around the world, the book gives an overview of the fate and transport of pesticides and their degradation in the environment. Detailing the sources, concentration, and hazards of residues, it examines their effects in humans, birds and mammals, fish, soil invertebrates, soil microflora, aquatic invertebrates, water, milk products, and more. The book also addresses endocrine-disrupting pesticides and explores biopesticides as alternatives to chemical pesticides. A review of data on the potential hazards of pesticides, this reference will be of interest to readers working in the areas of chemical crop protection and pollution management. It adds a balanced perspective to the debate between those who think that pesticides should be banned and those who consider the continued use of large quantities to be necessary for the survival of humanity.

The Death of Ramón González has become a benchmark book since its publication in 1990. It has been taught in undergraduate and graduate courses in every social science discipline, sustainable and alternative agriculture, environmental studies, ecology, ethnic studies, public health, and Mexican, Latin American, and environmental history. The book has also been used at the University of California-Santa Cruz as a model of interdisciplinary work and at the University of Iowa as a model of fine journalism, and has inspired numerous other books, theses, films, and investigative journalism pieces. This revised edition of The Death of Ramón González updates the science and politics of pesticides and agricultural development. In a new afterword, Angus Wright reconsiders the book's central ideas within the context of globalization, trade liberalization, and NAFTA, showing that in many ways what he called "the modern agricultural dilemma" should now be thought of as a "twenty-first century dilemma" that involves far more than agriculture.

An integrated analysis exploring current and relevant concepts, Fundamentals of Ecotoxicology: The Science of Pollution, Fourth Edition extends the dialogue further from the previous editions and beyond conventional ecosystems. It explores landscape, regional, and biospheric topics, communicating core concepts with subjects ranging from molecular to global issues. It addresses the increasing growth and complexity of ecotoxicological problems, contains additional vignettes, and employs input from a variety of experts in the field. Divided into 14 chapters, the book begins with an overall history of the field. It details the essential features of the key contaminants of concern today, including their sources. It examines bioaccumulation, the effects of contaminants at increasing levels of ecological organization, and the regulatory aspects of the field addressing the technical issues of risk assessment. The author includes appendices illustrating important environmental laws and regulations, and compiles key terms not already identified by section headings in the glossary. He also provides suggested readings at the end of each chapter and presents study questions at the end of the book. Fundamentals of Ecotoxicology: The Science of Pollution, Fourth Edition contains a broad overview of ecotoxicology, and provides a basic understanding of the field. Designed as a textbook for use in introductory graduate or upper-level undergraduate courses in ecotoxicology, applied ecology, environmental pollution, and environmental science, it can also be used as a general reference for practicing environmental toxicologists.

This report presents the assessment of Lakes Turkana, Tanganyika, Victoria and Malawi, the largest of the East African Rift Valley Lakes and among the oldest lakes in the world. The lakes are renowned for their high endemism and support a vital socio-economic service as a core for transportation, water supply, fisheries, recreation and tourism. Anthropogenic impacts have significantly altered the ecosystem function of these lakes. Lake Victoria, shared by three countries and influenced by two more in the catchment area, was targeted for causal chain and policy option analysis. Root causes related to pollution and overexploitation are discussed and policy options to address the driving issues are presented.--Publisher's description.
